On the storage side:
1)DX4700/4800 both have 4 drive bays – that provides for 8 TB today and soon
we’ll support 12 TB total when we finish testing 3 TB drives. Many vendors in the
hybrid class only offer 2 to 4 TB of storage. We have an edge there.

1)A fully maxed DX4800, recording all 18 channels 30 IPS, Analog 4 CIF and best

2))If we cut analog to 2 CIF/Medium quality and leave IP alone, we get 90 days

3)Tune analog down to 3 IPS, low quality, low resolution; IP down to 1 MB, and we

over 230 days.
